So accurate, in fact, that precipitation can be predicted at a distance of a few hundred meters. Radar measures and works extremely accurately. Meanwhile, the hit rate of the radar image is over 95%. We’ll take a look at how accurate these forecasts can be in a moment. Thanks to the broadly developed radar network and the modern technology behind the analysis of radar data, very accurate forecasts can be made with regard to the weather. ✔️ The weather map shows thunderstorms in addition to precipitation

✔️ The map differentiates between rain and snowfall ✔️ The radar is also displayed correctly on the smartphone and is mobile optimized ✔️ The area on the map can be zoomed in or out ✔️ The weather radar provides information about the past AND the future course of the rain areas In the following, you will find some points that indicate a good weather radar: How can you tell which radar is good and which one is better left alone? Whether on the Internet or in the various app stores, weather radars are offered in abundance these days. If you look around for a weather radar today, you will usually find one very quickly. Therefore, it is advisable to spread the radar measuring stations over a large area to get an accurate picture of the rainfall. In physics, this means the divergence of the radiation emitted by the station. The reason for this is the divergence of the emitted electromagnetic rays. Now it is the case that the accuracy of the measurement decreases with increasing distance. Only then can a concrete picture of precipitation in the area emerge. To display these results in a radar image, one needs not only one, but several stations at different locations. How is a weather radar created?Īs you already know, the radar station and its radar beams are used to measure the amount of water vapor present in a cloud. Only the use of new types of radar technologies, such as the Doppler radar, made this possible. …that the first weather radar was already built in the early 1940s? However, this type of weather radar could not accurately predict the intensity of the rain or the strength of the thunderstorm or storm. This central computer is responsible for processing all the collected data and using it to create a picture of the general weather situation. These weather stations are linked to each other and transmit the collected data to a central computer. To be able to make a concrete weather forecast and to collect and analyze the data over a large area, many different weather radar stations are required at various locations. What is a weather radar live?Ī weather radar live is a special type of radar that collects and analyzes data on the weather situation. You can also zoom in with your fingers or the mouse wheel. Use the + or – at the top right to zoom in. By finger pressure or mouse click you can move the area on the map. With the cursor at the bottom left in the center you can view the weather over time. The weather radar live itself displays cloud cover, current precipitation, storms, thunderstorms or tornados in real-time. This is how the weather radar live works: See for a more extensive discussion.Depending on the intensity, the precipitation appears on the rain radar in the colors blue (weak precipitation), green, yellow, orange (moderate precipitation), red or purple (very heavy precipitation). Thunderstorms and lightning strikes are indicated by a small lightning symbol. Weather radars can also pick up returns from nearby objects on the ground (ground clutter) and flying insects. So, rain will occur in some places (such as the western side of the Olympic Mountains) without it showing up on our loop. The beam can be blocked by mountains, and some areas are simply too far away from any radar. The coverage of the Pacific Northwest by weather radar is by no means uniform. Our loop shows the signals recorded by several radars in the northwest over the last several hours. High values of dbz (color scale to the right of the image) indicate large drops and heavy precipitation. Raindrops and snow produce reflections that become stronger as the size of the drop or flake increases. Weather radars send out pulses of microwave energy and listen between the transmitted pulses for part of that the energy to be reflected back to the radar.
